Environment

Product Version: 4.1

Resolution

1. List the TC server instance and find out its CATALINA_BASE

    davidz-a02:demo-instance dzhou$ tcserver list   
    Listing instances in '/Users/dzhou/Downloads/pivotal-tc-server/instances'
      demo-instance Info:
        Instance Name:                     demo-instance
        CATALINA_BASE:                     /Users/dzhou/Downloads/pivotal-tc-server/instances/demo-instance
        CATALINA_HOME:                     /Users/dzhou/Downloads/pivotal-tc-server/runtimes/tomcat-9.0.63.A.RELEASE
        JAVA_HOME:                         /Library/Java/JavaVirtualMachines/jdk-14.0.2.jdk/Contents/Home
        tc Runtime Version:                9.0.63.A.RELEASE
        tc Server Version:                 4.1.16.RELEASE
        tc Server Installation Directory:  /Users/dzhou/Downloads/pivotal-tc-server/standard-4.1.16.RELEASE
        Running Status:                    Running as PID 38749

2. Switch to the directory of the TC server instance

cd /Users/dzhou/Downloads/pivotal-tc-server/instances/demo-instance/webapps/

3. Create a folder ”manager"

mkdir manager

4. Inside the "manager" folder, copy the configuration of manager app from tc Server Installation Directory, which can be found in step 1.

cd manager
cp -R /Users/dzhou/Downloads/pivotal-tc-server/standard-4.1.16.RELEASE/templates/manager-tomcat-9/webapps/manager/ .

5. Go back to the instance base folder and add user/password to create an account

cd ../../
vim conf/tomcat-users.xml

Here is a sample:
​​

davidz-a02:demo-instance dzhou$ more ./conf/tomcat-users.xml
<?xml version="1.0"?>
<tomcat-users>
  <user username="admin" password="changeme" roles="admin,manager,manager-gui"/>
</tomcat-users>

6. Allow this TC server instance in privileged mode

davidz-a02:demo-instance dzhou$ more conf/context.xml
<?xml version="1.0"?>
<Context privileged="true">
    <!-- Default set of monitored resources -->
    <WatchedResource>WEB-INF/web.xml</WatchedResource>
    <!-- Uncomment this to disable session persistence across Tomcat restarts -->
    <!--
            <Manager pathname="" />
            -->
    <!-- Uncomment this to enable Comet connection tacking (provides events
                 on session expiration as well as webapp lifecycle) -->
    <!--
            <Valve className="org.apache.catalina.valves.CometConnectionManagerValve" />
            -->
    <WatchedResource>${catalina.base}/conf/web.xml</WatchedResource>
</Context>

7. Restart this TC server instance

tcserver restart demo-instance

8. Open a browser at http://127.0.0.1:8080/manager/html with the user/password in step 5. The following page indicates the manager app deployed successfully!
